The valve body 12 has a main passage and the valve member 20 is movable between a closed position in which the valve member 20 engages with a seat face 16 of the valve seat 14 to substantially prevent flow of fluid along the main passage, and an open 10 position in which the valve member 20 is spaced from the seat face 16. The valve assembly may be a poppet valve.
